Continue pt-set topology and measure theory
T0,1,2,3,4
好多def，啲人點記，and need to find example
我估我要畫個簡單picture嚟記，我估analysis多數搞t2記t2，聽講algebraic topology班人搞最weak嘅t0拎最generalized嘅result，但唔關我事啦應該
我覺得唔知係咪metric space嘅language太靚，依家叫我搞抽象嘅topology，好唔慣
weak topology咪non metrizable 
主要用Neighbourhood將def同proof再更新一次
仲未學
好似係聽日
學左point set topology然後讀functional會順D
Point set topology我跟住接住measure theory，啱啱自己證咗locally finite 令union of closure is closed
Measure theory之後就會停一陣，最後返complex analysis多一次
嗰次明到analytic continuation就會正式收工
可能因為佢in general可以唔使俾numerical value，純粹俾neighbourhood 就搞掂
其實metric space後期都唔駛架
